The scale will transmit stable weights above gross zero once for each transition from
Start-Up Gross Zero to the stable weight. When an object is placed on the platform and
the scale stabilizes at the weight, the scale will transmit the weight data and then
disable the output. The output will remain disabled until the object is removed.
Once the scale returns to Start-Up Gross Zero, the data output is enabled to transmit
the next stable, nonzero weight.
This differs from the AP1 mode, in that the scale must return to zero to reenable the
output.
The Auto-Print 2 mode is useful with printers or computers where high quality weight
samples are required with a minimum of operator intervention.
5.2.4 Auto-Print 3 (AP3)
This output mode is similar to Auto-Print 2. The difference is that the zero reset point
for is based upon displayed zero rather than "Start-Up Gross Zero".
This mode is useful for when the amount of tare weight on the scale will vary.
5.2.5 Continuous Transmission ("CNT")
The scale transmits weight data once each scale update.
Since there is no qualification of the data as to stability or overrange, an additional
status character is transmitted with the weight data. This status character appears at
the end of the message after the last weight unit character and before the carriage
return/line feed.
This output mode is used with computers and data loggers where real-time monitoring
of the weight is necessary.
5.2.6 Latch On Demand (“L.O.d.”)
Data transmission is initiated by pressing the PRINT button. The PRINT button is active
regardless of stability and overload condition of the scale.
The print request is latched and the data is transmitted upon the first valid stable
weight.
5.3 DATA OUTPUT FORMAT
The Model 8000 can be set up to support different data output formats. All characters
are standard ASCII. The data output can be selected to output 8 or 7 databits with no,
odd, or even parity and 2 stop bits.
5.3.1 Format 1
Data output message format 1- "lb", "kg", "oz" and "g":
STX POL DATA SP lb/kg/oz/g grs/net ST* CR+LF
